Authorities say Parrotti got away with about $38,000 from the four holdups in Binghamton, Whitney Point and Sayre and Scranton in Pennsylvania. They say he claimed to be armed and passed notes to tellers demanding cash in each case.

Parrotti faces up to 20 years in prison and fines up to $250,000 on each of the counts. He's set to be sentenced on May 23 in federal court in Binghamton.
